  • Toxic chemicals used in mining

    Copper: Sulfuric Acid is used for leaching of copper from oxide ore, and some sulfide ores. The leaching solution is claimed to be diluted and recycled. However, it is recycled into lined ponds of high toxic levels of sulfuric acid. The sulfuric acid can enter the soil and groundwater through breaks, spills, tears in liners.

  • Neutralization of Acid Mine Water and Sludge Disposal

    The acid water is formed as a result of bacterial oxidation when pyrites are exposed to oxygen and water after or during the mining process. Currently, acid water is neutralized with lime before it is re-used (e.g. for coal washing in the coal mining industry) or discharged into public streams. The following disadvantages can be linked to lime
